I posted earlier today about crooked aldermen—and some honorable ones—I have known of. Here's a handy cheat sheet, published in 2009 by the political science department of the University of Illinois at Chicago, of corrupt aldermen in Chicago from 1973 through 2008. Thirty were convicted during that time, and two more were indicted but died before trial. In most instances, the corrupt acts began while they were aldermen.

You'll find them listed here in Appendix 1 of this report (page 14). There also are bios of each offender. Twenty-five of those convicted were products of the Democratic machine, three were Republicans, and only two were independents—Lawrence Bloom of the Fifth Ward, and Fred Hubbard of the Second Ward, who defected to the machine shortly after his election.
